Ingredients

Scale
  • 200g (7 oz) chocolate biscuits, crushed (Arnott’s Tim Tams recommended or any chocolate-covered biscuit)
  • 150g (5.3 oz) unsalted butter, melted
  • 1 can (395g) sweetened condensed milk
  • 2 tablespoons (15g) Dutch-processed cocoa powder
  • 200g (7 oz) dark chocolate (at least 70% cocoa), chopped
  • 2 tablespoons (30ml) golden syrup
  • A pinch of sea salt (optional)
  • 1 teaspoon vanilla extract

Instructions

  1. Crush the chocolate biscuits until mostly fine crumbs with some small chunks remain. Use a food processor or place biscuits in a ziplock bag and crush with a rolling pin.
  2. Melt the butter in the microwave or on the stove, then combine it with the crushed biscuits in a large bowl.
  3. Stir in the sweetened condensed milk, cocoa powder, golden syrup, and vanilla extract until the mixture is evenly coated and sticky. Add more condensed milk if too dry.
  4. Line a 20x20cm (8×8 inch) baking pan with baking paper, leaving an overhang on two sides for easy removal.
  5. Press the biscuit mixture firmly and evenly into the base of the pan using the back of a spoon or a flat-bottomed glass.
  6. Chop the dark chocolate into small pieces. Melt the chocolate gently over a double boiler or in the microwave in short bursts, stirring until smooth. Optionally add a tablespoon of butter or cream for gloss.
  7. Pour the ganache over the biscuit base and spread evenly with a spatula. Sprinkle a pinch of sea salt on top.
  8. Place the pan in the fridge and chill for at least 2 hours until the ganache is set.
  9. Use a sharp knife warmed under hot water and wiped dry to slice the set slice into neat squares.

Notes

Crushing biscuits unevenly adds a nice crunch. Use low heat when melting chocolate to avoid burning. Press biscuit base firmly but not too hard. Chill for at least 2 hours or overnight for best texture. Warm knife before slicing to prevent cracking.
